Thanks Tcampbell. The thing is, that was the first day out with the camera and I was getting the hang of it. I liked the 3rd picture the most out of all of them, but I noticed after uploading and enlarging it to full size that he was out of focus, bummer. The reason I say it was my first day out is that I wasn't worrying about composition much and more about taking a bunch of shots trying to find out what works in what light. The picture of the guy on the surfboard thing was just kind of by chance, it was one quick shot I took when he wasn't looking. He was coming in from far off the lake and I didn't want to bother him by taking his picture. Now that I think back I should have payed more attention to the composition and not trying to take a bunch of pictures I could pick and choose from later.
Now that you are the 1000th person I have seen suggest that book, Understanding Exposure, I must assume that it is a good read and I will get it soon.
I appreciate the feedback. I didn't put a lot of thought into these pictures, now that I feel I have a better hang of it, I can focus more on getting the right shot and not worry so much about perfect exposure every time. I found myself fiddling with all my settings and seemingly every shot was taken as a sort of test shot to see how it came out. I did try to apply the rule of thirds, but I didn't really think much into the picture as I was going crazy how to get the exposure set. Again, I really appreciate the feedback, it really does help.
